SURGICAL TABLE.

SPECIFICATION forming part of Letters Patent No. 620,318, dated February28, 1899.

Application filed March 5,1898. Serial No. 672,714. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL HAVNAR, a citizen of the United States,residing at Painesville, in the county of Lake and State of Ohio, haveinvented certain new and useful Improvements in Surgical Tables; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in surgical tables for treatinglocomotor ataxia and kindred diseases; and it has for itsobject toprovide a simple and effective apparatus whereby the patient may reclinein a comfortable position while being treated.

lVith this and other objects inview my invention consists in anapparatus of this class embodying certain novel features ofconstruction, combination, and arrangement of parts, as. will behereinafter fully described and claimed.

In the accompanying drawings, forming part of this specification, Figure1 is a plan view of a surgical table constructed in accordance withmyinvention. Fig. 2 is aside elevational view of same. Fig. 3 is alongitudinal section. Fig. 4 is a horizontal section of the head portionof the table. Fig. 5 is a plan view of the scale and coacting parts ofthe adjusting mechanism. transverse Section through the sliding leaf,showing the saddle turned down.

Like letters of reference designate corresponding parts throughout theseveral figures of the drawings.

A represents a table supported on legs I) and comprising in itsconstruction the two parallel side bars 13 and end cross-bars 0,connected to the corner-posts D, to which the legs are secured in theusual manner. At the head of the table is a rigid top piece E and at thefoot thereof a rigid top piece E, and arranged between the same is asliding central leaf or top section F, mounted on rollers f, adapted totravel grooved ways f, formed in the side bars B. The rigid top piecesare provided with depending guides g 9- H I representsupporting-brackets arranged, respectively, at the head and foot of thetable and each consisting of a horizontal Fig. 6 is a.

body portion H I, provided at one end with a vertical arm h i. The bodyportion of the bracket H is bifurcated from the arm to form the parallelshanks j, which are fitted to slide in slots in the guide 9 and endcross-bar O at the head of the table, and the inner ends of said shanksare provided with stop-lugs k to limit the outward movement of saidbracket. The shanks are also formed with a series of openings Z for thereception of a pin m, whereby the bracket may be adjusted as desired andheld against inward movement. also bifurcated to form shanks j, whichare fitted to slide in slots in the guide g and adjoining cross-bar O atthe foot of the bed, and these shanks are likewise provided withstop-lugs 70, adapted to limit their outward movement, and with openingsZ for the reception of a pin m, having the same function as thecorresponding pin on the bracket H.

The vertical arm h of the bracket H is formed with a threaded orifice,in which operates a hand-screw n. This screw is provided at its innerend with a neck 0 and a head 0, and this neck projects through anopening in the cross-bar of a link p, which is connected with an eye 19on one end of a scale or indicator q and is held from disengagement bythe head. By this construction it will be seen that the screw has aswivel connection with the scale and may turn freely independentlythereof. The scale bar or beam q of the indicator, which carries thepointer, is connected with a strap-guide g to which a strap 7", designedto engage the head of the patient, is attached.

The arm 71 of the bracket I is formed with a slot, in which is locatedafriction pulley or roller .9, around which passes a strap 6, carryingbuckle-loops a, designed to engage the feet of the patient.

The manner of using my invention is as follows: The patient reclinesupon his back on the table, with his body resting on the sliding centralleaf-section, the head and legs being supported, respectively, by thestationary top pieces E E. The top piece may be padded or provided witha head-rest. The brackets H I are next adjusted to suit the length ofthe patient, the straps r a secured about the head and feet of thepatient, and

The body portion of the bracket I is then the screw is operated tostretch the neck, back, and legs at one operation. This mode oftreatment is much more satisfactory than the method heretofore employedof suspending the patient, as the patient reclines in a comfortableposition and is thereby enabled to stand the treatment for a longerperiod. The legs, too, are stretched at the same time as the neck, andthe pulling strain may be regulated as desired and determined byconsulting the scale.

The object of the sliding central leaf or top section F is to permit thepatient to assume a comfortable position at the start Without raisinghis body and also to allow free hackand-forth movement of the body asthe pulling mechanism is operated.

It is sometimes desirable to stretch the legs of the patient Withoutstretching his entire body, and to this end I provide a saddle V,provided at its rear end with an eye 1), whereby it is pivoted toswingin a transverse opening W, formed in the sliding section F. This saddlenormally projects below the said section, as shown in Fig. 6, but may beswung up to the position shown in Fig. 3 to take between the legs andserve as a seat-support. The saddle is also provided at opposite sideswith loops w, to which straps a: are attached. When the saddle is inuse, the free ends of these straps are connected directly to thestrap-guide g of the scale bar or beam g. If desired, however, thesestraps may be secured about the body of the patient and the slidingsection F connected with the scale-beam or an additional strap providedto connect the eye 3 on the cantle of the saddle with said scale-beam.The operation with this construction will be readily understood.

I desire it understood that I do not limit my invention to the specificconstruction and arrangement of parts herein shown and described, butreserve to myself the right to make such changes and alterations asclearly fall Within the spirit and scope of my invention.

Having thus fully described my invention, what I claim as new anduseful, and desire to secure by Letters Patent, is

1. A surgical table for the purpose described, comprising a table-frameproper, a sliding central section thereon, a saddle carried by saidsliding section, fastening means at the foot of the table to confine thefeet of the patient, stretching mechanism at the head of the tableprovided with means for confining the head of the patient, and means forconnecting the saddle directly to said pulling mechanism, whereby theparts may be connected up to stretch the entire body or legs only of thepatient, substantially as described.

2. A surgical table for the purpose described, comprising a table-frameproper provided with brackets at the head and foot thereof, a centralsection mounted to slide thereon, a saddle carried by the slidingsection and adapted to be raised and lowered to project above orbelowthe same, foot-straps connected to the bracket at the foot of the table,stretching mechanism carried by the bracket at the head of the table, ascale connected with the said mechanism and carrying a head-strap, andmeans for connecting the saddle to said scale, whereby the parts may beconnected up to stretch the entire body or legs only of the patient andthe pulling strain exerted determined with certainty in either case,substantially as described.

3. In a surgical table, the combination of a table-frame, a slidingleaf-section, a scale or indicating device, a saddle pivotally swung inan opening in said sliding leaf, and means for connecting said saddle tothe said scale or indicating device, substantially as described.

4. In a surgical table, the combination of a table frame provided withstationary top pieces at the head and foot thereof, a sliding centralsection, adjustable brackets at the head and foot of the table,foot-straps connected with the latter bracket, an operatingscrew mountedin the head-bracket and provided at its inner end with a swivel, a scalehaving a sliding beamor bar movable through one end thereof andconnected to said swivel, and a head-strap connected to a swivel on theother end of the beam, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

SAMUEL I'IAVNAR.
